Lattice isomorphisms between certain sublattices of continuous functions

Let $C(X,I)$ be the lattice of all continuous functions on a compact Hausdorff space $X$ with values in the unit interval $I=[0,1]$. We show that for compact Hausdorff spaces $X$ and $Y$ and (not necessarily contain constants) sublattices $A$ and $B$ of $C(X,I)$ and $C(Y,I)$, respectively, which satisfy a certain separation property, any lattice isomorphism $\varphi : A \longrightarrow B$inducesahomeomorphism$\mu: Y \longrightarrow X$. If, furthermore, $A$ and $B$ are closed under the multiplication, then $\phi$ has a representation $\phi (f)(y)=m_y(f(\mu (y)))$, $f\in A$, for all points $y$ in a dense $G_{\delta }$ subset $Y_0$ of $Y$, where each $m_y$ is a strictly increasing continuous bijection on $I$. In particular, for the case where $X$ and $Y$ are metric spaces and $A$ and $B$ are the lattices of all Lipschitz functions with values in $I$, the set $Y_0$ is the whole of $Y$.
